Problems solved by technology

The above two methods cover two methods of anti-felting treatment. The former introduces grafting groups on the wool surface, and the hand feeling of the fabric will be significantly affected by the existence of the coating, while the latter will inevitably lead to relaxation of the fiber structure.

Embodiment 1

[0027] The preparation method of the single-sided anti-felting wool fabric of embodiment 1 comprises the steps:

[0028] S1: Scrape and coat chitosan acid solution on one side of the wool fabric, the concentration of chitosan in the chitosan acid solution is 0.5%, dry naturally, wash and dry, and place the wool fabric in a low-temperature atmosphere for plasma treatment ;

[0029] S2: Configure chitosan silica sol finishing solution. The main components of chitosan silica sol finishing solution are chitosan, silicon dioxide, organic polyacids, water, and the pH of chitosan silica sol finishing solution is 5. The percentage by weight of chitosan in the polysaccharide silica sol finishing solution is 0.5%, and the silicon content of the chitosan silica sol finishing solution is 1.5%;

[0030] S3: Spray and soak the surface of the other side of the wool fabric with water, apply the chitosan silica sol finishing solution obtained in S2 on the wetted surface of the wool fabric and...

Embodiment 2

[0035] Embodiment 2 is based on embodiment 1, difference is: the chitosan concentration in the chitosan acid solution is 2.5%; The weight percent is 3%, and the silicon content of chitosan silica sol finishing liquid is 3.5%.

[0036] In the medium and low temperature plasma treatment process of S1, the non-polymerizable gas in the chamber of the plasma treatment device is argon, the applied voltage discharge frequency is 13.75MHz, the power is 200W, and the treatment time is 20s.

[0037] The preparation process of chitosan silica sol finishing solution in S2 is: dissolving chitosan in the chitosan mixed solution in the organic acid aqueous solution, adding water to the water glass to dilute, then adding the chitosan mixed solution to the water glass under stirring In the solution, adjust the pH value with an organic acid, and oscillate ultrasonically for 20 minutes; the organic acid is itaconic acid; the coating method in S3 is transfer coating.

Embodiment 3

[0039] Embodiment 3 is based on embodiment 2, difference is: the chitosan concentration in the chitosan acid solution is 1.5%; The weight percent is 1.7%, and the silicon content of chitosan silica sol finishing liquid is 2.5%.

[0040] In the medium and low temperature plasma treatment process of S1, the non-polymerizable gas in the chamber of the plasma treatment device is ammonia gas, the applied voltage discharge frequency is 13.75MHz, the power is 100W, and the treatment time is 100s.

[0041] The preparation process of chitosan silica sol finishing solution in S2 is: dissolving chitosan in the chitosan mixed solution in the organic acid aqueous solution, adding water to the water glass to dilute, then adding the chitosan mixed solution to the water glass under stirring In the solution, adjust the pH value with an organic acid, and oscillate ultrasonically for 5 minutes; the organic acid is citric acid; the coating method in S3 is transfer coating.

Abstract

The invention discloses a preparation method of a single-side-antifelting wool plus material. The preparation method of the single-side-antifelting wool plus material comprises the following steps of the pretreatment of a wool plus material, the preparation of chitosan silica sol finishing liquid, finishing, drying and the like. According to the preparation method of the single-side-antifelting wool plus material, a protective effect is formed for the wool plus material by adopting a chitosan solution, so that the surface damage of a fiber is a little after the wool plus material is subjected to plasma treatment in a low-temperature atmosphere; the influences on the original water repellency of a wool fiber are few; by finishing the chitosan silica sol finishing liquid on a surface on one side of the wool plus material, a condensation reaction is generated among components in the finishing liquid; a thin film with certain rigidity is cross-linked on the surface of the wool plus material, so that the wool plus material has a single-side-antifelting performance; the thin film formed on the surface of the wool plus material also has flexibility adapting to the plus material; a binding area between a film layer and the plus material is large; the binding strength is favorable; the wool plus material to which the thin film is bound is long in service life; chitosan per se has the characteristics of antibiosis and moisture absorption; therefore, the finished wool plus material has the advantages of good hand feeling, antibiosis, moisture absorption, air permeability and the like.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a method for preparing a single-sided anti-felting wool fabric. Background technique [0002] Wool has many excellent properties such as good elasticity, strong moisture absorption, good warmth retention, and soft luster. Wool fabrics are noble in style and superior in wearability. However, unfinished wool fabrics will shrink when they are continuously squeezed and rubbed during washing, which will cause changes in the appearance of the fabric, such as shrinkage of the fabric size, hairiness of the woolen surface, and chaotic texture. The continuous accumulation of the above changes will affect the appearance and quality of the fabric. The wearing performance limits the application fields of wool to a certain extent. The reason for the felting of wool fabrics is traditionally believed to be mainly caused by the directional friction effect caused by the wool scale layer structur...
